Bacula Admin Tool (bat) does not work well with Qt 4.6.2 in Lucid

The new version of Bacula (5.2.0) to be released in about a month has a number
of fixes, and will work perfectly with Qt 4.6.2 (Lucid) where I have done the
development work. There have been quite a number of enhancements and a lot
of stability improvements in bat 5.2.0.

As I previously reported, bat uses Qt, which has some important compatiblity
problems between versions. Hopefully the new 5.2.0 bat will also work on
Maveric. If not, I will be releasing a depkgs-qt-4.6.2 that can be used to
compile bat on any Ubuntu release.

Kern

Kern, does this mean that there is an explicit fix in the code of 5.2.0 that will make this problem go away on Qt 4.6.2 ?

While I do think we should put 5.2.0 in backports when it arrives, if the fix is simple it might be worth patching 5.0.1 so it works in lucid.

This one is really hard to confirm as I don't have any files to restore in my test bacula. Is there a shorter test case?

I'm going to mark this as Incomplete, pending a shorter test case and/or answers from Kern. If its too hard to test, and/or too hard to fix in lucid, it might just have to be a "Won't Fix".

Actually since it has been confirmed upstream I'm marking it as Confirmed, Importance Medium, since there doesn't seem to be a workaround.

There have been a very large number of changes to bat from 5.0.x to 5.2.0,
including new features, bug fixes, and particularly seg fault fixes. I am
sorry, I don't remember the specifics, and since I did not explicitly
reproduce the reported bug, I am not sure there is an explicit fix, but I
think so.

There were a lot of changes, and I believe we have a significant number in the
Director too, so any backporting might not be easy. You are free to try
backporting but it is not something that I am personally going to do.

I don't know as I haven't explicitly reproduced the reported bug.

OK. I am not sure what your procedure is -- it might be good to note "fixed
in 5.2.x" providing that is really the case.

Hm. Sounds like this one may not get backported.

The procedure is to mark the main bug task Fix Released, but then track
each release of the package before that individually. Won't Fix means the
bug is in that version, but we're not going to fix it.

OK, your procedures are different from ours, which is OK.

We normally indicate to the user that it is fixed in a future version. That
is all I was trying to say. No problem however you do it :-)

Right, we don't really have the luxury of putting people on new upstream
releases, though we'll indicate the status of the bug upstream so users
can go and get the new version if they want.

It *would* be good to link this to lucid-backports once 5.2.0 releases
so people can at least see that this bug would be fixed by a backport
of bacula 5.2.0.
